All five players were acquired by the Red Sox within the last year and De Jesus, Carpenter and Stewart were small pieces of some of Boston's biggest trades of the season. De Jesus was picked up as part of the blockbuster deal with the Dodgers in August, Carpenter came from the Blue Jays as part of the John Farrell trade package, and Stewart as part of the deal that sentKevin Youkilis to the White Sox in June. Valencia, meanwhile, was picked up in a trade with the Twins in August while Rosario was picked up off waivers from the Marlins last month.
